Digital Road Map Database is a basic element of intelligent transport systems. Japan Digital Road Map Association (JDRMA) was established in 1988 to establish the standard for digital road map (DRM) and to produce a DRM database in Japan. Car navigation is currently the largest application of DRM. There are about 20 navigation systems now on the market. About 400,000 navigation systems had been sold until 1993. In the beginning, navigation systems were sold together with cars, but recently aftermarket systems are expanding sales. Police departments, fire departments, ambulance services and taxi companies use location systems which use DRM. Significant applications of DRM are expected to come in the future in the planning and management of roads.
